description: Running your function code in the Azure Functions Flex Consumption plan provides virtual network integration, dynamic scale (to zero), and reduced cold starts.
# Customer intent: As a developer, I want to understand the benefits of using the Flex Consumption plan so I can get the scalability benefits of Azure Functions without having to pay for resources I don't need.

134
+**Host**: There's a 30-second time out for app initialization. When your function app takes longer than 30 seconds to start, you might see gRPC-related `System.TimeoutException` entries logged. You can't currently configure this time out. For more information, see [this host work item](https://github.com/Azure/azure-functions-host/issues/10482).
135

+**Durable Functions**: Azure Storage is currently the only supported [storage provider](./durable/durable-functions-storage-providers.md) for Durable Functions when hosted in the Flex Consumption plan. See [recommendations](./durable/durable-functions-azure-storage-provider.md#flex-consumption-plan) when hosting Durable Functions in the Flex Consumption plan.

+**Virtual network integration** Ensure that the `Microsoft.App` Azure resource provider is enabled for your subscription by [following these instructions](/azure/azure-resource-manager/management/resource-providers-and-types#register-resource-provider). The subnet delegation required by Flex Consumption apps is `Microsoft.App/environments`.

+**Triggers**: All triggers are fully supported except for Kafka and Azure SQL triggers. The Blob storage trigger only supports the [Event Grid source](./functions-event-grid-blob-trigger.md). Non-C# function apps must use version `[4.0.0, 5.0.0)` of the [extension bundle](./functions-bindings-register.md#extension-bundles), or a later version.
